Hi,
I'm working on a budget to mid-range PC buyers guide and I'm currently testing the EP45-DS3L to see if it's worth a recommendation.
I'm having trouble though getting any significant overclock out of an E7200. I've had good experiences with the P35 Ds3, P35 DQ6 and X38 DQ6 so I'm not new to GB and OC in general, but I can't figure out the problem here.
Here's my hardware:
EP45 DS3L (BIOS F8 Final)
Corsair HX520 PSU
OCZ 2x2GB 1066 or Cellshock 2x1GB 1000 CL4 (runs at relaxed timings)
ATI 3870
Sunbeam Core Contact Freezer (CPU temp is definitely not a problem)
At standard voltages 275 FSB is no problem but 300 won't POST even with significantly increased voltages. I tried different RAM slots and the two different RAM kits but the problem seems not to be RAM related (RAM Multi is set poperly, see below)
I filled out the BIOS template with the changes I made:
MB Intelligent Tweaker(M.I.T.)

I can't figure out what the problem is. I have not tried the a different CPU yet or tried this CPU on a different board, but I can't really believe that the CPU is unable to reach 300 FSB.
Thanks for your help!
